Enterprise architecture frameworks and implementation strategies
Re-aligning the economics of enterprise software, Software-as-a-Service (SaaS) is changing the nature of how enterprise application architectures are planned, deployed and managed in organizations globally. SaaS is the application delivery layer of the broader cloud computing protocol stack that includes Infrastructure-as-a-Service (IaaS) at its base, followed by Platform-as-a-Service (PaaS) at the midpoint. SaaS is at the top level of the cloud computing architecture, providing Application Programmer Interface (API) support for user and machine interfaces (Beimborn, Miletzki, Wenzel, 2011). When the term cloud computing is used, it refers to this entire protocol stack. Enterprises are increasingly reliant on cloud computing due to the cost advantages over traditional enterprise applications. Foremost among the many economic factors favoring cloud computing, the nascent business models in SaaS-based application deployment support a wide spectrum of operating expense (OPEX) based pricing and payment approaches including usage-based pricing (Bala, Carr, 2010). These payment models are re-ordering the enterprise application landscape, a key finding from the research presented in this analysis.
